Docker本地存储库删除不释放空间

Question

我正面临一个问题。如果我做错了什么，请告诉我。

我创建了一个本地 docker 存储库(开发、文件系统)并尝试将一些本地镜像推送到相同的位置。

本地镜像保存在存储库中，GET 请求显示 JSON 内容。

但是，我想从存储库中删除这些图像，为此我使用了 HTTP DELETE 请求，从存储库中删除了“库”和图像。
问题是被推送到 repo 的图像占用的空间没有被释放。

我已经删除了运行存储库的容器以及存储库镜像本身，但空间仍未释放。
奇怪的是，在任何系统目录中都看不到相同的内容，即使我在/中执行 du -hs/* 也是如此。

附上 repo 查询的内容。

Answer 1

可能的答案:
Deleting images from a private docker registry

无法尝试这是否有效，因为我删除了我的虚拟机。

不过还是感谢 Konrad Kleine 的帮助
